Anomem.的识别这组光谱中最显著的特征是在约100 nm处的吸收峰（2a型）。844厘米1，具有中等或强强度，这可能与α D-吡喃葡萄糖结构的存在相关，而不是其β-端基异构体。该峰由α-D-吡喃葡萄糖及其还原甲基醚、甲基α-D-吡喃葡萄糖苷及其甲基醚、α-D-葡糖胺衍生物（表1）和含有α-键的低聚和多聚葡聚糖（表3）显示，但这些化合物不显示该峰
DISCUSSIONIdentijcation of Anomem.-The most striking feature of the set of spectra is the absorption peak (type 2a) at ca. 844 cm.-l, of moderate or strong intensity, which can be correlated with the presence of the aD-glucopyranose structure, as opposed to its p-anomer. This peak, which is displayed by aD-glucopyranose and its reducing methyl ethers, by methyl aD-glucopyranoside and its methyl ethers, by derivatives of aD-glucosamine (Table 1), and by oligo-and poly-glucosans containing a-linkages (Table 3), but not by those compounds
